Stone Fruit
I fermented an ESB with this strain and really liked the results. It accentuated the stone fruit characteristics of the First Gold hops. I plan to brew a slightly different version of this ESB recipe again with only this strain to let the peachy, apricoty esters shine. I fermented at 67-68F for the first 3 days and then slowly stepped up by one degree per day to 72 to finish attenuation.

great yeast supplier for conan
Have used others that don't attenuate well on the first generation and are finicky but the imperial was great. No attenuation problems and made a great NEIPA.

Worked great
I was a little concerned give the not so great reviews but I'm glad I tried it. Worked awesome in my topper clone. Didn't have any issues with the can. Attenuation and lag time were awesome. Would use again.

WOW!
First time using this yeast. I used it in a North Eastern IPA. It was the perfect match for the style and what I was looking for. Nothing but great reviews from everyone. They all take a drink and then the WOW face.

HOLY COW!
This yeast is incredible! Smells like everything we love about juicy IPAs. Smells of mango, pineapple, oranges, etc. I want an air freshener in my house of this stuff! Tab comes off super easy. This is one of the most active yeasts I've used. My only complaint is the lack of directions on a can. Instructions such as temperature storage, pitching temperature, etc. Also, my only roadblock was at the bottom of the can it was completely coagulated. I had to sterilize a spoon, fill with some chilled wort, and homogenize the remaining yeast.

All in all, do your research before using this and you can't go wrong. This strain is one of my favorites now.

Finally giving up
This company is local for me and thus I was excited when their cans first started becoming available. I love the fact that I could easily ferment my standard IPA recipe without having to make a starter, but... I have officially stopped using this company's yeast and I am back to using starters. I have tried every method imaginable and followed the company's directions explicitly but have still have had several cans pretty much explode when opening to pour into my fermenter. Keep in mind these can were coming straight from the fridge to the fermenter and were not shaken at all, but the last can I used (and will ever use) sprayed yeast and the packaging liquid so forcefully that it hit the 9 foot ceiling in my house. Needless to say, my wife is supportive of my decision to abandon this company. Also, even if the can doesn't explode upon opening, there will always be a substantial amount of yeast stuck to the lid and inside the can after pitching, this has resulted in the can's lid falling off of the pull tab and into the fermenter on one occasion as well. I would, and have warned fellow home brewers to steer clear of this yeast company, as there are serious issues than can easily be avoided by using white labs/wyeast and making a starter.

Color me impressed!
This review is for homebrewers like me who are hesitant to try yeast outside of their comfort zones. I rely heavily on a proven track record and reviews before throwing yeast into my precious wort. With Imperial's Barbarian, I'm glad I pulled the trigger.

I used Barbarian in a 5 gallon batch IPA which used centennial for bittering and then centennial, simcoe, and citra continuously hopped from 20 minutes until flameout. I then dry hopped with an ounce of each for 6 days before bottling.

A few things to note, I had heard that Barbarian could have a problem fermenting out, so I pitched some Safale-05 at a week in to help it along after my gravity readings pointed to a possible stalling. Can I confirm that it had actually stalled? No, but I didn't want to wait to find out. Second, medium flocculation here is generous. I cold crashed and at bottling it was murkier than a hef. I didn't want to fine with gelatin or anything to preserve as much hop flavor and aroma as possible. Not necessarily a negative characteristic of the yeast, but if you're obsessed with clarity, you've been warned.

Now, the finished product. A-MAZ-ING. Seriously, I can't praise it enough. I would give it 4.5 stars if I could but the threat of stalling, coupled with the clumsy can lid that sprayed a bit of yeast on opening, kept me from giving it a perfect score.

This was one juicy IPA, with delightful aromas reminiscent of mangos and peaches, followed by an initial grapefruit flavor, and a sweet pineapple aftertaste on the tongue. If this beer was commercially available, I'd buy it, and I wouldn't buy most of the beer I brew. If you are on the fence about this yeast, just go for it. I certainly didn't regret, and I don't think you will either.

Can Design
Yeast started well and seems to be chugging away. The big issue with this is the opening mechanism on the cans. used 4 cans and the tab snapped on each one before I could open the lid at all. Had to use a screwdriver to get it open and hopefully did not contaminate the yeast... lid tab needs to be stronger.

Just to add to the review...The yeast itself is a BEAST. 4 cans on a 25 gallon batch and in 4 days almost down to 1.010...Better results than I have had with a similar "Vermont" yeast.
